Pull IDA updates from Matthew Wilcox:
 "A better IDA API:

      id = ida_alloc(ida, GFP_xxx);
      ida_free(ida, id);

  rather than the cumbersome ida_simple_get(), ida_simple_remove().

  The new IDA API is similar to ida_simple_get() but better named.  The
  internal restructuring of the IDA code removes the bitmap
  preallocation nonsense.

  I hope the net -200 lines of code is convincing"

Almost all files in the kernel are either plain text or UTF-8 encoded.  A
couple however are ISO_8859-1, usually just a few characters in a C
comments, for historic reasons.

This converts them all to UTF-8 for consistency.

When command line parsing fails in the while loop in do_event_pipe()
because the number of arguments is incorrect or because the keyword is
unknown, an error message is displayed, but bpftool remains stuck in
the loop. Make sure we exit the loop upon failure.

As with many other projects, we use some shmalloc allocator.  At some
point we need to make a part of allocated pages back private to process.
And it should be populated straight away.  Check that (MAP_PRIVATE |
MAP_POPULATE) actually copies the private page.
